Disclosed herein are non-natural amino acids and dolastatin analogs that include at least one non-natural amino acid, and methods for making such non-natural amino acids and polypeptides. The dolastatin analogs can include a wide range of possible functionalities, but typically have at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Also disclosed herein are non-natural amino acid dolastatin analogs that are further modified post-translationally, methods for effecting such modifications, and methods for purifying such dolastatin analogs. Typically, the modified dolastatin analogs include at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Further disclosed are methods for using such non-natural amino acid dolastatin analogs and modified non-natural amino acid dolastatin analogs, including therapeutic, diagnostic, and other biotechnology use.
本文公开了包括至少一种非天然氨基酸的非天然氨基酸和多拉他汀类似物,以及制造这种非天然氨基酸和多肽的方法。多拉他汀类似物可包括多种可能的官能团,但通常具有至少一个肟基、羰基、二羰基和/或羟胺基团。本文还公开了经翻译后进一步修饰的非天然氨基酸多拉他汀类似物、进行此类修饰的方法以及纯化此类多拉他汀类似物的方法。通常,修饰的多拉他汀类似物包括至少一个肟基、羰基、二羰基和/或羟胺基团。进一步公开的是使用此类非天然氨基酸多拉他汀类似物和修饰的非天然氨基酸多拉他汀类似物的方法,包括治疗、诊断和其它生物技术用途。
